       This manual page documents briefly the gfscompare command.

       gfscompare2D,  gfscompare3D  -  computes  the  difference  between  the  solutions in FILE1 and FILE2 for
       variable VAR.

       These programs follow the usual GNU command line syntax, with  long  options  starting  with  two  dashes
       (`-').  A summary of options is included below.

       -x,--mixed
              Compute error only in mixed cells.

       -mV,--min=V
              Set minimum of color scale to V (used with -S).

       -MV,--max=V
              Set maximum of color scale to V.

       -a,--abs
              Output the absolute value of the error field.

       -C,--constant
              Apply  a  constant  shift to one of the field, minimizing the error between the two fields (useful
              for pressure).

       -w,--not-weighted
              Do not use area-weighted norm estimation.

       -c,--centered
              Use error estimation for cell-centered variables.

       -pP,--period=P
              Shifts FILE1 by P along the x axis.

       -H,--histogram
              Output (error,volume) pairs for each cell used to compute the error norms.

       -o,--output
              Output a GTS representation of the error field.

       -S,--squares
              Output an OOGL representation of the error field.

       -G,--gnuplot
              Output a gnuplot representation of the error field.

       -t,--triangulate
              Use center of mass triangulation.

       -l,--log
              Output the log10 of the absolute value of the error field.

       -fL,--full=L
              Compare only leaf cells descendants of a cell full at level L or all full leaf cells if L = -1.

       -r,--refined
              Display error norm on the finest grid.

       -n,--nocheck
              Do not check solid fractions.

       -gC,--gradient=C
              Use the C component of the gradient of VAR.

       -v,--verbose
              Display difference statistics and other info.

       -h,--help
              Display the help and exit.
